Personal Statement · Application Essay · written by claude-sonnet-5-5 · 379 words

Technology shapes nearly every moment of our lives, yet it often fails the people it is meant to serve. I first understood this when I watched my grandmother struggle to use a banking app. She was intelligent, capable, and determined, but the interface assumed knowledge she had no reason to possess. Tiny icons, unlabeled menus, and confusing error messages left her feeling that she was the problem. I realized then that she wasn't failing the technology; the technology was failing her. That moment set me on a path toward human-computer interaction.

Since then, I have looked for opportunities to bridge the gap between people and the systems they use. In my introductory programming courses, I enjoyed writing code, but I found myself most energized when I asked what happened after the code was finished: who would use it, in what context, and with what frustrations? When I volunteered to redesign my university club's website, I interviewed members, observed how they searched for information, and tested prototypes with them. Seeing a once-confusing event registration process become something people could complete in under a minute was deeply satisfying. It showed me that thoughtful design is not decoration; it determines whether a tool empowers or excludes.

I am drawn to HCI because it unites disciplines I care about: psychology, design, engineering, and ethics. It asks technical questions alongside human ones. How do we build systems that are accessible to people with disabilities? How can we design AI tools that are transparent and trustworthy? How do we create technology that respects attention and wellbeing rather than exploiting them? These questions grow more urgent as interfaces move beyond screens into voice, gesture, and immersive environments.

I want to study HCI formally to gain rigorous research methods, deepen my understanding of cognition and behavior, and learn from faculty who are shaping the field. I am eager to collaborate with peers from diverse backgrounds, because good design depends on many perspectives.

My long-term goal is to work on inclusive technologies, whether in research or industry, that make people feel capable rather than confused. I want to build systems that meet people where they are, so that no one else feels the way my grandmother did. Studying HCI is the next step toward making that vision real.

Technology influences almost every aspect of our lives, even though it frequently fails the people it is supposed to help. The first time I realised this was when I saw my grandmother having difficulty using a banking app. Although she was intelligent, capable and determined, the programme assumed that she had knowledge which was completely unnecessary for her to have. The small icons, the menus without labels, and the confusing error messages made her feel as though it was her fault. At that point I came to see that it was not she who was failing the technology; rather, it was the technology that was failing her. Ever since that moment I have been determined to work in the field of human-computer interaction.

Since that time I have sought out ways to reduce the gap between people and the systems they use. Although I enjoyed writing code in my beginner programming classes, I was most enthusiastic about finding out what happened after the code had been completed: who would be using it, in what situation, and what frustrations they would have? When I agreed to redesign my university club's website, I interviewed the members, watched the way they searched for information, and put prototypes through tests with them. It was very satisfying to see an event registration procedure which had previously been confusing become one that people could finish in under a minute. This experience proved to me that careful design is not just about decoration; it decides whether a tool enables or excludes people.

I have been attracted to HCI since it brings together a number of fields that I am interested in: psychology, design, engineering, and ethics. It poses both technical and human questions. For example, how can we design systems that are accessible to people who have disabilities? How can we create AI tools that are transparent and trustworthy? How can we develop technology that respects people's attention and their wellbeing rather than taking advantage of them? The importance of these questions increases as interfaces go beyond screens and become voice, gesture, and immersive environments.

My aim is to study HCI in a formal way so as to acquire rigorous research methods, improve my understanding of cognition and behaviour, and learn from the faculty members who are helping to shape the field. I am looking forward to working with peers from a variety of backgrounds since good design relies on many different perspectives.

My aim is to be involved in the development of inclusive technologies—whether in a research or industrial context—so that people feel capable not merely confused. I would like to create systems that address people at their current level, in order that nobody else may have the same experience as my grandmother did. Taking up the study of HCI is the next move towards making that vision a reality.

Technology touches almost every facet of our lives but it does not serve the people it was built for. My grandma had a hard time using a banking app and this is when I understood it for the first time. She was smart, competent and determined but the interface demanded information she had no reason to know. She felt like the problem, especially when greeted with tiny icons, no labels on menus and too many meaningless error messages. At that point, I understood she was not failing the technology — the technology was failing her. This moment paved the way for me to head into HCI as a field.

I continue to search for opportunities that connect humans to the systems they operate since then. I liked writing code in my intro programming classes, but I found my energy highest when I asked what would happen in the wake of the codes completion - who is going to use this code, where are they using it, and being frustrated by aspet of using it? While redesigning a website for my university club, I interviewed members, observed their information-seeking behaviours, and tested prototypes with them. It was very satisfying to see something that once took 10+ minutes for people to register for an event became a process they could complete in less than a minute. That taught me thoughtful design is not decoration; it determines whether a tool helps or harms.

HCI is all these things that I am interested in (psychology, design, engineering, ethics) melded together. It asks technical questions in addition to the human ones. In what way can systems be created to include those with disabilities? Transparent and Trustworthy AI tools. How will we design technology that respects attention and wellbeing in contrast to exploiting them? As interfaces move beyond the screen into voice, gesture, and immersive environments, these questions become even more pressing.

I hope to study HCI formally because I want rigorous research training, a better understanding of cognition and behavior, and teachers who are leaders in the field. I am excited about working with people from a variety of backgrounds, because good design is multi-faceted and multi-voiced.

In the long term, I want to build inclusive technologies – in research or industry that empowers people as opposed to baffling them. I want to create systems that meet people where they are so that no one else feels this way the way my grandmother did. The next step on the road to that vision is characterising HCI.
